Use an Error** for request to let the caller handle error reporting.
This will also allow to inform the frontend of a backend error.

The TPM backend uses a GThreadPool to handle IO in a seperate
thread. However, GThreadPool isn't integrated with Qemu main loops,
making it unnecessarily complicated to deal with.
Qemu has a AIO threadpool, that is better integrated with loops and
various IO functions, provides completion BH by default etc.
Remove the only user of GThreadPool from qemu, use AIO threadpool.
Note that the backend:
- no longer accepts queing multiple requests (unneeded so far)
- increase ref to itself when handling a command, for extra safety
- tpm_backend_thread_end() is renamed tpm_backend_finish_sync() and
will wait for completion of BH (request_completed), which will help
migration handling.

The sparc architecture does not allow misaligned loads and will
segfault if you try them. For example, this function:
static inline uint32_t tpm_cmd_get_size(const void *b)
{
return be32_to_cpu(*(const uint32_t *)(b + 2));
}
Should read,
return ldl_be_p(b + 2);
As a general rule you can't take an arbitrary pointer into a byte
buffer and try to interpret it as a structure or a pointer to a
larger-than-bytesize-data simply by casting the pointer.
Use this clean up as an opportunity to remove unnecessary temporary
buffers and casts.

It does not make much sense to limit these commands to the legacy 'vlan'
concept only, they should work with the modern netdevs, too. So now
it is possible to use this command with one, two or three parameters.
With one parameter, the command installs a hostfwd rule on the default
"user" network:
hostfwd_add tcp:...
With two parameters, the command installs a hostfwd rule on a netdev
(that's the new way of using this command):
hostfwd_add netdev_id tcp:...
With three parameters, the command installs a rule on a 'vlan' (aka hub):
hostfwd_add hub_id name tcp:...
Same applies to the hostfwd_remove command now.

QEMU can emulate hubs to connect NICs and netdevs. This is currently
primarily used for the mis-named 'vlan' feature of the networking
subsystem. Now the 'vlan' feature has been marked as deprecated, since
its name is rather confusing and the users often rather mis-configure
their network when trying to use it. But while the 'vlan' parameter
should be removed at one point in time, the basic idea of emulating
a hub in QEMU is still good: It's useful for bundling up the output of
multiple NICs into one single l2tp netdev for example.
Now to be able to use the hubport feature without 'vlan's, there is one
missing piece: The possibility to connect a hubport to a netdev, too.
This patch adds this possibility by introducing a new "netdev=..."
parameter to the hubports.
To bundle up the output of multiple NICs into one socket netdev, you can
now run QEMU with these parameters for example:
qemu-system-ppc64 ... -netdev socket,id=s1,connect=:11122 \
-netdev hubport,hubid=1,id=h1,netdev=s1 \
-netdev hubport,hubid=1,id=h2 -device e1000,netdev=h2 \
-netdev hubport,hubid=1,id=h3 -device virtio-net-pci,netdev=h3
For using the socket netdev, you have got to start another QEMU as the
receiving side first, for example with network dumping enabled:
qemu-system-x86_64 -M isapc -netdev socket,id=s0,listen=:11122 \
-device ne2k_isa,netdev=s0 \
-object filter-dump,id=f1,netdev=s0,file=/tmp/dump.dat
After the ppc64 guest tried to boot from both NICs, you can see in the
dump file (using Wireshark, for example), that the output of both NICs
(the e1000 and the virtio-net-pci) has been successfully transfered
via the socket netdev in this case.

Packet size some time different or when network is busy.
Based on same payload size, but TCP protocol can not
guarantee send the same one packet in the same way,
like that:
We send this payload:
------------------------------
| header |1|2|3|4|5|6|7|8|9|0|
------------------------------
primary:
ppkt1:
----------------
| header |1|2|3|
----------------
ppkt2:
------------------------
| header |4|5|6|7|8|9|0|
------------------------
secondary:
spkt1:
------------------------------
| header |1|2|3|4|5|6|7|8|9|0|
------------------------------
In the original method, ppkt1 and ppkt2 are different in size and
spkt1, so they can't compare and trigger the checkpoint.
I have tested FTP get 200M and 1G file many times, I found that
the performance was less than 1% of the native.
Now I reconstructed the comparison of TCP packets based on the
TCP sequence number. first of all, ppkt1 and spkt1 have the same
starting sequence number, so they can compare, even though their
length is different. And then ppkt1 with a smaller payload length
is used as the comparison length, if the payload is same, send
out the ppkt1 and record the offset(the length of ppkt1 payload)
in spkt1. The next comparison, ppkt2 and spkt1 can be compared
from the recorded position of spkt1.
like that:
----------------
| header |1|2|3| ppkt1
---------|-----|
| |
---------v-----v--------------
| header |1|2|3|4|5|6|7|8|9|0| spkt1
---------------|\------------|
| \offset |
---------v-------------v
| header |4|5|6|7|8|9|0| ppkt2
------------------------
In this way, the performance can reach native 20% in my multiple
tests.

In various place we don't correctly check if the device supports MSI or
MSI-X. This can cause devices to be advertised with MSI support, even
if they only support MSI-X (like virtio-pci-* devices for example):
ethernet@0 {
ibm,req#msi = <0x1>; <--- wrong!
.
ibm,loc-code = "qemu_virtio-net-pci:0000:00:00.0";
.
ibm,req#msi-x = <0x3>;
};
Worse, this can also cause the "ibm,change-msi" RTAS call to corrupt the
PCI status and cause migration to fail:
qemu-system-ppc64: get_pci_config_device: Bad config data: i=0x6
read: 0 device: 10 cmask: 10 wmask: 0 w1cmask:0
^^
PCI_STATUS_CAP_LIST bit which is assumed to be constant
This patch changes spapr_populate_pci_child_dt() to properly check for
MSI support using msi_present(): this ensures that PCIDevice::msi_cap
was set by msi_init() and that msi_nr_vectors_allocated() will look at
the right place in the config space.
Checking PCIDevice::msix_entries_nr is enough for MSI-X but let's add
a call to msix_present() there as well for consistency.
It also changes rtas_ibm_change_msi() to select the appropriate MSI
type in Function 1 instead of always selecting plain MSI. This new
behaviour is compliant with LoPAPR 1.1, as described in "Table 71.
ibm,change-msi Argument Call Buffer":
Function 1: If Number Outputs is equal to 3, request to set to a new
number of MSIs (including set to 0).
If the “ibm,change-msix-capable” property exists and Number
Outputs is equal to 4, request is to set to a new number of
MSI or MSI-X (platform choice) interrupts (including set to
0).
Since MSI is the the platform default (LoPAPR 6.2.3 MSI Option), let's
check for MSI support first.
And finally, it checks the input parameters are valid, as described in
LoPAPR 1.1 "R1–7.3.10.5.1–3":
For the MSI option: The platform must return a Status of -3 (Parameter
error) from ibm,change-msi, with no change in interrupt assignments if
the PCI configuration address does not support MSI and Function 3 was
requested (that is, the “ibm,req#msi” property must exist for the PCI
configuration address in order to use Function 3), or does not support
MSI-X and Function 4 is requested (that is, the “ibm,req#msi-x” property
must exist for the PCI configuration address in order to use Function 4),
or if neither MSIs nor MSI-Xs are supported and Function 1 is requested.
This ensures that the ret_intr_type variable contains a valid MSI type
for this device, and that spapr_msi_setmsg() won't corrupt the PCI status.

qemu-system-ppcemb has been once split of qemu-system-ppc to support
CPU page sizes < 4096 for some of the embedded 4xx PowerPC CPUs.
However, there was hardly any OS available in the wild that really
used such small page sizes (Linux uses 4096 on PPC), so there is
no known recent use case for this separate build anymore. It's
rather cumbersome to maintain a separate set of config switches for
this, and it's wasting compile and test time of all the developers
who have to build all QEMU targets to verify that their changes did
not break anything.
Except for the small CPU page sizes, qemu-system-ppc can be used as
a full replacement for qemu-system-ppcemb since it contains all the
embedded 4xx PPC boards and CPUs, too. Thus let's start the deprecation
process for qemu-system-ppcemb to see whether somebody still needs
the small page sizes or whether we could finally remove this unloved
separate build.

The Xilinx ZynqMP SoC has two main processing systems in it. The ARM
processing system (which is already modeled in QEMU) and the MicroBlaze
Power Management Unit (PMU). This is the inital work for adding support
for the PMU.
The PMU susbsystem runs along side the ARM system on hardware, but due
to architecture limitations in QEMU the two instances are seperate for
the time being.
Let's follow the same setup we do with the ARM system, where there is an
SoC device and a ZCU102 board. Although the PMU is less board specific
we are still going to follow the same split as maybe in future we can
connect the PMU device to the ARM ZCU102 board. As the machine will be
fairly small let's keep them both together in one file.

Previously if no device tree was passed to microblaze_load_kernel() then
qemu_find_file() would try to find a NULL pointer. To avoid this put a
check around qemu_find_file().
